[英]Layout above another
我正在嘗試在Android應用程序中創建此頁面:
至此,我最終得到以下布局:
<?xml version="1.0" encoding="utf-8"?>

<android.support.design.widget.TextInputLayout

android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.TextInputEditText
android:id="@+id/default_text"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:singleLine="true"
android:theme="@style/AppTheme" />
</android.support.design.widget.TextInputLayout>
<android.support.design.widget.TextInputLayout

</android.support.design.widget.TextInputLayout>
</LinearLayout>
</android.support.v7.widget.CardView>
</LinearLayout>
</LinearLayout>
</FrameLayout>
結果是這樣的:
問題是當鍵盤對准焦點時,我得到了以下結果,將AdjustResize放在清單中:
你知不知道怎么:
1)避免在鍵盤聚焦時遮蓋輸入2)像第一個數字一樣放置按鈕(在底部邊距上方)
如果您對如何改進xml有任何建議,那將是不錯的選擇,因為我是android xml的新手。
先感謝您

2)嘗試使用ConstraintLayout
( docs )創建平面布局而不是分層布局(這對於您的應用程序性能更好)
